DynaPrep MDSF PrecisePrep Tool Slide The DynaPrep MDSF PrecisePrep Heavy Wall Slide is an addition to the growing system of modular accessories for the DynaPrep MDSF split frame system. The PrecisePrep Heavy Wall tool slide is used in conjunction with the MDSF to single point and counterbore heavy wall pipe. It will create a wide variety of weld preps using an innovative configurable template and follower system. Preps include bevel, compound bevels, narrow angle bevels, and when finished with the appropriate tooling, J-preps.Designed to replace more traditional bridge slide designs that span the diameter, the PrecisePrep Heavy Wall eliminates concerns for internal obstruction clearances often found on vessels and heat exchangers. Like most modules for the DynaPrep MDSF the PrecisePrep can be used across all ring sizes. It can be optionally equipped for remote control machining, an important consideration in hostile or radioactive environments.
